Static Routing Using 5 Routers in Packet Tracer

What is static and dynamic routing?

Static routing is when you statically configure a router to send traffic for particular destinations in preconfigured directions. Dynamic routing is when you use arouting protocol such as OSPF, ISIS, EIGRP, and/or BGP to figure out what paths traffic should take.

What is the next hop?

Next hop is a routing term that refers to the next closest router a packet can go through. The next hop is among the series of routers that are connected together in a network and is the next possible destination for a data packet.

What is the use of static routing?

Static routing is a form of routing that occurs when a router uses a manually-configured routing entry, rather than information from a dynamic routing traffic. ... Static routing can also be used in stub networks, or to provide a gateway of last resort.

How do you set up a static route?

Click Advanced Routing button on the left side of the screen, then select Static Routing List(in 54Mbps Wireless Router, the name of button is Static Routing). Input destination network, subnet mask, default gateway, select status and save it. Please refer to following introduction to input parameter.

Uses

Static routing may have the following uses:

Static routing can be used to define an exit point from a router when no other routes are available or necessary. This is called a default route.
Static routing can be used for small networks that require only one or two routes. This is often more efficient since a link is not being wasted by exchanging dynamic routing information.

Static routing is often used as a complement to dynamic routing to provide a failsafe backup in the event that a dynamic route is unavailable.
Static routing is often used to help transfer routing information from one routing protocol to another (routing redistribution).

Disadvantages

Static routing can have some potential disadvantages:

Human error: In many cases, static routes are manually configured. This increases the potential for input mistakes. Administrators can make mistakes and mistype in network information, or configure incorrect routing paths by mistake.
Fault tolerance: Static routing is not fault tolerant. This means that when there is a change in the network or a failure occurs between two statically defined devices, traffic will not be re-routed. As a result, the network is unusable until the failure is repaired or the static route is manually reconfigured by an administrator.
Administrative distance: Static routes typically take precedence over routes configured with a dynamic routing protocol. This means that static routes may prevent routing protocols from working as intended. A solution is to manually modify the administrative distance.

Administrative overhead: Static routes must be configured on each router in the network(s). This configuration can take a long time if there are many routers. It also means that reconfiguration can be slow and inefficient. Dynamic routing on the other hand automatically propagates routing changes, reducing the need for manual reconfiguration.
